I tried to find the same situation on my machine and what shall I say?
I found it in my "$USERPROFILE/My Documents" directory.
The ACL of my "My Documents" dir gives me full access, byt Cygwin shows
that the directory is not writable. When debugging, I found to my
honest surprise that the "My Documents" directory has the good old
"Read-Only" DOS attribute set.
For as long as I'm working on Cygwin's security stuff, the R/O attribute
removes the write bits from the file mode. What happens in stat(2) is
basically:
read ACL ==> st_mode = 0700
is DOS R/O set ==> st_mode = 0500
Apparently this was never correct for directories(*). Argh! Why did
never anybody notice it before?!?
Thanks for the report. I'll apply a fix in CVS. For the time being the
best workaround for you would be to remove the R/O attribute from your
"My Documents" directory:
$ attrib "$USERPROFILE\My Documents"
